Description
Technical field
The utility model relates to a kind of residual current circuit breaker, especially a kind of plug-in type residual current circuit breaker.
Background technology
Residual current circuit breaker is a kind of conventional electric switch, is mainly used in the various places such as industry, business, residential houses.Arrange leakage tripping device in residual current circuit breaker to realize electric leakage to thread off, when leakage current exceedes predetermined value, leakage tripping device action, now owing to affecting by residual current circuit breaker inner space, push rod on leakage tripping device is linked by a torsion push rod and snap close usually, the kind of drive of this spline structure, to the material of push rod, profile angle, the range demands of leakage tripping device iron core action is very high, be difficult in making hold, part push rod is plastics compactings simultaneously, the arm of force is long, effect passed to the transmission of power bad, so when often causing product to occur leakage current, leakage tripping device can not make moving contact of breaker system disconnect reliably, product is made to there is great potential safety hazard.
The test button of existing residual current circuit breaker is become by two panels test film, test button, a test turriform groups of springs.There is the defects such as electric clearance is little, cost is high, the life-span is short in this test button device.
Summary of the invention
For above-mentioned reasons, the purpose of this utility model is to provide a kind of simple and reasonable, plug-in type residual current circuit breaker easy to process.
For achieving the above object, the utility model adopts a kind of plug-in type residual current circuit breaker, comprise housing, operating mechanism in housing is set, electromagnetic system, leakage tripping device, electromagnetic system comprises coil, coil brace, dynamic iron core, static iron core, push rod, coil winding is on coil brace, dynamic iron core and static iron core are arranged in coil brace, push rod is arranged in static iron core, push rod rear end and dynamic iron core are connected, push rod between dynamic iron core and static iron core is outside equipped with electromagnetic system spring, push rod front end withstands on operating mechanism, leakage tripping device is arranged on rear side of the dynamic iron core of electromagnetic system, the connecting axle at leakage tripping device center is connected with push rod through dynamic iron core, described housing is provided with test button, sensitive switch is provided with in test button.
The utility model is set to described housing both sides further and forms radiating groove, the both ends of the surface of the through housing of radiating groove.
The utility model is set to described housing be provided with socket and flexible fastening pillar further, the inserted sheet that on socket, formation two is relative, socket is provided with the jump ring for being clamped in opposite directions by inserted sheet, socket is inlaid in one end, housing bottom surface, inserted sheet is exposed at outside housing, and flexible fastening pillar is arranged on the housing bottom surface other end.
The beneficial effects of the utility model are that leakage tripping device is directly connected with the push rod of electromagnetic system, make leakage tripping device and electromagnetic system realize linking and thread off; Test button adopts ready-made sensitive switch, and not only structure is simple, and stable performance, easy to assembly; Surface of shell arranges radiating groove, improves the radiating effect of residual current circuit breaker; Adopt the mounting structure of socket and flexible fastening pillar to make circuit breaker can meet special installation code abroad, and simple installation, to stablize, reliably.
